This series of products is an electromagnetically controlled industrial device that is an automated base component for controlling fluids. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the media. The solenoid valve can be used with different circuits to achieve the desired control, while the precision and flexibility of the control can be guaranteed.

Third, the performance characteristics:
1, solenoid valve spool is stainless steel material, piston structure, strong resistance to action fatigue.
2, the piston ring design structure is more scientific, made of special materials, will not be stuck by impurities in the medium,
High performance sealing and long life.
3, the metal piston and the metal valve cavity do not produce direct friction, will not be stuck, the installation direction of the valve body is not limited.
4, the special coil, the coil is not easy to burn.
5, reasonable sealing material and structure, better sealing performance.
6, restart after a long-term stop action, the action is equally sensitive.
7, the interface size is usually national or international standards, customers can customize special interfaces.
8, the use of conventional products has a lifespan of more than 1 million times.
9. A solenoid valve having a jacketed sealed piston ring and a high performance combined sealed piston ring.
10, ultra-low temperature solenoid valve with a minimum temperature resistance of -200 °C.
Fourth, the working principle:
Normally closed type: When the coil is energized, the pilot spool is closed, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure of the lower chamber, and the solenoid valve is opened; when the coil is de-energized, the pilot spool is reset by the spring. The pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed.
Normally open type: When the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston orifice and the thrust of the return spring, and the solenoid valve is closed. When the coil is de-energized, the pilot spool is reset by the spring, the pilot hole is opened, the upper chamber of the valve is relieved, the piston is pushed by the medium pressure of the lower chamber, and the solenoid valve is opened.
note:
1. Pilot-operated piston solenoid valve requires that the medium passing through the solenoid valve must have pressure (the medium has no pressure and is not suitable for this valve). The solenoid valve on our side is to ensure that the medium has a pressure of 0.1 kg to work properly.
2. There are two sources of force for opening the main piston of the pilot piston solenoid valve. One is the magnetic force generated after energization, and the second is the pressure pushing of the medium.
These two forces must exist at the same time to ensure the normal operation of the pilot piston solenoid valve.
